Model R718PA4
User Manual
Introduction
R718PA4 is a Netvox Class A device based on LoRaWAN™ protocol and compatible with the LoRaWAN protocol. R718PA4 can be connected to a hydrogen sulfide sensor with RS485 to report the concentration of hydrogen sulfide collected by the device to the corresponding gateway.
LoRa Wireless Technology:
Lora is a wireless communication technology dedicated to long-distance and
low power consumption. Compared with other communication methods, the LoRa
spread spectrum modulation method greatly increases to expand the
communication distance. Widely used in long-distance, low-data wireless
communications. For example, automatic meter reading, building automation
equipment, wireless security systems, industrial monitoring. Main features
include small size, low power consumption, transmission distance, anti-
interference ability, and so on.
LoRaWAN:
LoRaWAN uses LoRa technology to define end-to-end standard specifications
to ensure interoperability between devices and gateways from different
manufacturers.

Set up Instruction
On/Off
| Power on | DC12V adapter |
|---|---|
| Turn on | DC12V power supply, the green indicator flashing once means turn on |
successfully.
Turn off (Restore to factory setting)| Press and hold the function key for 5
seconds and the green indicator flashes 20 times.
Power off| Remove DC12V adapter.
Note:| 1. At 1st to 5th seconds after power-on, the device will be in
engineering test mode.
2. On/off interval is suggested to be about 10 seconds to avoid the
interference of capacitor inductance and other energy storage components.
Network Joining
Never joined the network| Turn on the device to search the network to join.
The green indicator stays on for 5 seconds: success The green indicator
remains off: fail
---|---
Had joined the network| Turn on the device to search the previous network to
join.
The green indicator stays on for 5 seconds: success The green indicator
remains off: fail
Fail to join the network (when the device is on)| Suggest checking the device
verification information on the gateway or consult your platform service
provider.
Function Key
Press and hold for 5 seconds| Restore to factory setting / Turn off The green
indicator flashes 20 times: success The green indicator remains off: fail
---|---
Press once| The device is in the network: the green indicator flashes once and
sends a report The device is not in the network: the green indicator remains
off
Data Report
The device will send a version package report immediately after power-on.
Then, it will send a report data with the concentration of hydrogen sulfide
after it is powered on for the 20s.
The device sends data according to the default configuration before any other
configuring.
Default setting:
Maxime: Max Interval = 3min = 180s
Minime: The MinTime configuration is not available.
*But the software has restrictions, MinTime must be configured a number greater than 0.
Note:
- The cycle of the device sending the data report is according to the default.
- R718PA4 reports the concentration of hydrogen sulfide. Please refer to Netvox LoRaWAN Application Command document and Netvox Lora Command Resolver
http://loraresolver.netvoxcloud.com:8888/page/index to resolve uplink data.

Report Configuration Example:
-
Configure the report Maxime = 1min (The MinTime configuration is useless, but it needs to be set greater than 0 because of the software limitation.)

Installation
This product comes with a waterproof function.
When using it, users can attach the backside to the iron surface, or use
screws to fix both ends to the wall.
Note: To install the battery, use a screwdriver or similar tool to assist
in opening the battery cover.
-
The device has a built-in magnet (as the figure below). It can be attached to the surface of an iron object conveniently and quickly when it is installed.
In order to make the device installation more secure, use screws (purchased) to fix the device to the wall or other surface (such as the installation diagram). The device is
screwed by two screws in the middle (purchased by users).
Note:
Do not install the device in a metal shielded box or in an environment with other electrical equipment around it to avoid affecting the wireless transmission of the device.
-
The device periodically reports the data according to Max Time. The default Max Time is 1 hour. Note: Max Time can be modified by the downlink command, but it is
not recommended to set this time too small to avoid excessive battery drain. -
The device can be used in scenarios such as:
• Sewer
• Pig farm
• Chemical plant
• Wastewater treatment plant
• Exploration drilling channel
Important Maintenance Instruction
Kindly pay attention to the following in order to achieve the best maintenance of the product:
- Keep the equipment dry. Rain, moisture, and various liquids or water may contain minerals that can corrode electronic circuits. In case the device is wet, please dry it completely.
- Do not use or store in dusty or dirty areas. This way can damage its detachable parts and electronic components.
- Do not store in an excessive heat place. High temperatures can shorten the life of electronic devices, destroy batteries, and deform or melt some plastic parts.
- Do not store in an excessively cold place. Otherwise, when the temperature rises to normal temperature, moisture will form inside which will destroy the board.
- Do not throw, knock or shake the device. Treating equipment roughly can destroy internal circuit boards and delicate structures.
- Do not wash with strong chemicals, detergents, or strong detergents.
- Do not paint the device. Smudges can make debris block detachable parts up and affect normal operation.
- Do not throw the battery into the fire to prevent the battery from exploding. Damaged batteries may also explode.
All the above suggestions apply equally to your device, batteries, and
accessories.
If any device is not operating properly.
Please take it to the nearest authorized service facility for repair.
